Major Repairs

Major repairs are significant expenditures on an existing long-term asset that do more than keep it running in its normal condition. A cost counts as a major repair when it extends the asset's useful life beyond the original estimate, increases its productive capacity, or improves the quality or efficiency of its output. Because such work benefits several future periods, the cost is capitalized by adding it to the asset's carrying amount, and then depreciated over the asset's remaining life. The idea overlaps with the entry on extraordinary repair, a term many textbooks use for the same category; this entry concentrates on how to distinguish major repairs from routine costs and how they are recorded.

Major repairs contrast with ordinary repairs and maintenance, such as oil changes, painting and replacing small parts, which keep an asset working as intended and are charged to expense when incurred. The distinction matters because it moves costs between the balance sheet and the income statement and therefore affects reported profit.

Accountants usually ask several questions:

• Does the work extend the asset's life? Replacing the engine in a ten-year-old truck that would otherwise be scrapped adds years of use.
• Does it increase capacity or output? Adding a wing to a warehouse or upgrading a machine to run faster increases what the asset can do.
• Does it improve quality or reduce operating costs? Installing a modern control system that cuts energy use is an improvement.
• Is the amount material? Many companies set a capitalization threshold, such as $5,000, below which all repairs are expensed regardless of their nature.

If the answer to the first three questions is no, the cost is usually an ordinary repair, however large it is. A roof patch costing $20,000 that simply restores the roof to its previous condition is still maintenance.

A printing company owns a press that cost $600,000, has accumulated depreciation of $400,000 and is being depreciated at $50,000 a year, with four years of life left. The company spends $120,000 on a rebuild that extends the press's remaining life from four to eight years. The rebuild is a major repair. The entry debits the equipment account (or, in some textbooks, accumulated depreciation) $120,000 and credits cash $120,000. The press's book value rises from $200,000 to $320,000.

The new annual depreciation is:

With no residual value, this is $320,000 divided by 8, or $40,000 a year. The change is treated prospectively as a change in estimate; earlier years are not restated. Had the company expensed the $120,000, its profit for the year would have been $120,000 lower and future depreciation expense lower.

Under IFRS (IAS 16), the cost of replacing a significant component of an asset is capitalized and the carrying amount of the replaced part is removed, an approach called component accounting. US GAAP allows a similar approach but is less prescriptive. In both, the cost of a major inspection or overhaul, such as an aircraft engine check, can be capitalized as a separate component.

For US tax purposes, the tangible property regulations issued by the Internal Revenue Service in 2013 require costs to be capitalized when they result in a betterment, a restoration or an adaptation of a unit of property to a new use. They also provide safe harbors, including a de minimis election for low-cost items and a routine maintenance safe harbor, which let many repairs be deducted immediately.

Treating maintenance as a major repair inflates fixed assets and current profit, and spreads costs into future years. The best-known case is WorldCom, which in 2002 admitted it had capitalized several billion dollars of ordinary operating costs. Analysts compare repair expense with capital expenditure over time to spot unusual shifts, and auditors test large repair invoices to confirm that capitalized costs genuinely improve the asset rather than simply maintain it. The effect of capitalized amounts appears on the income statement only gradually, through depreciation.
